I saw some of you have stunning macro pictures that are extremely sharp. I suck at lightroom and my images are appearing very crudy, some help please? I'm a beginner in lightroom so some tips would be nice.

I'm not super-skilled myself but hopefully this is helpful.

Post processing can improve a photo but we can only enhance sharpness that's already there.

The DOF is very thin in macro shots, it's a constant challenge. You've got to choose angles and compositions with thin DOF in mind. You've got the eyes of the closest shrimp in focus, but the angle of the shot guarantees that the rest of his body won't be in focus and the one behind him will not be in focus.

For little creature shots you might pick an angle from the side and get most of the subject in focus, or try to shoot head-on and get a "portrait" of the face.

You could stop down to improve DOF, but of course that slows shutter speed. To compensate for slow shutter speed you can use flash, or pick stationary subjects and use a tripod.

What focal length and aperture did you use for your shot?

There is an interesting technique called
focus stacking which I believe that
you will find useful. As usual, Google is
your friend...

At f/2.8 your DOF is of course very skinny. Stopping down would get much more of the shrimp in focus, and make composition easier.

I notice your shot was at ISO 800, I think the T2i can shoot higher ISOs before losing much quality, that would allow you to stop down a couple of notches "for free".

Keep practicing, that's the great thing about digital. Macro shooting on film must have been very frustrating!

Your try (crop):

My (more aggressive) try (crop):

As said it's mostly a problem of the thin DOF
Do you have Lightroom 4 or 3? If you have LR4 I could show you my settings.

Imho ISO800 is a good ISO for free-hand shooting as it lets you more reserves for PP than higher ISO. Best way is to use a diffuse flash and ISO100-to ISO400.

And of course we can add "sharpness", but it makes only sense if the resolution is already there. Sharpness is a subjective mixture of resolution(details), contrast and acutance - and we can add contast and acutance by PP but no resolution.

I have lightroom 4. I guess I'll try to stop down for next time.
